Exactly... And I'm somewhat surprised that I haven't
yet(?) seen any commentary in this thread/subject from the
fxp driver author/maintainer, David Greenman...
Anyway, sometime back, I asked him specifically about this card
(& a couple of others) & he told me the following (paraphrased):
1. *None* of Intel's "intelligent" network cards (those
with an onboard CPU such as the i960) are supported.
2. The "enhanced" features of the 8255x chips
(specifically, the hardware TCP-checksum support on cards
like the Pro100+ Server Adapter) are also *not* supported.
IIRC/IIUC, the reason is that the information necessary for
device driver developers to support these cards/adapters/features
is only available from Intel under NDA. :-(
